The filing and enforcement of liens (different states refer to these with different terms) to secure payment for services or goods against a workers' compensation award is complex and filled with special rules - this category is for questions and discussion of this special area of work comp law.

You should purchase the 1999 OMFS because it contains the ground rules for paying for physician services. Upon receipt, augment it with the online modifications effective 07/12/2002. Although you can find payment rates online, you'll need the ground rules if you want to defend liens properly. For instance, the tiered-reimbursement formula for physical medicine is in the 1999 OMFS and I don't believe it's posted on the DIR website (someone will surely tell us if I'm wrong).

On a separate note, the medical-legal fee schedule is in Regs. 9793 - 9795. They are relatively simple, and there is no excuse for any defense attorney, judge, medical provider or lien representative not to memorize them.
